Gear Systems for Abrasive Cutting Machines
Abrasive cutting machine gears are exposed to extreme operating conditions, including extreme heat and high levels of dust. In addition, the pressure applied to the cutting disc during abrasive cutting must be reliably accommodated by the gearbox casing without the casing or the drive shaft deforming in any way. The very high output speeds of up to 4000 rpm also require a particularly robust design of the anti-friction bearings. Eisenbeiss has developed a proven gear system concept for this purpose, already reliably implemented many times over in industrial applications.
Since the motor and gearbox are arranged parallel to the cutting wheel on cutting machines, the Eisenbeiss gear system concept includes a deflector bevel gear stage at the input shaft to efficiently transmit the rotational movement.
During the cutting process, the gear is slowly tilted, affecting the level of the liquid grease inside. An external liquid grease unit with integrated cooling ensures that gears and bearings are always adequately supplied with oil and that the operating temperature of the transmission remains stable in every position.
